Trailer bearings

[TrueBlue]

Hi all,
Just wondering, any ideas as to what bearings most likely I would have in the trailer.
13" Holden PCD wheels and braked.
Appears to be a 45mm square axle.
I think it may even be an original trailer, that was a tilt but that has been bolted up to make it fixed.

I'm suspecting most likely SL Ford due to the axle size and weight as most say their boat and trailers weigh in around the 1200 mark?
Just a thought you guys may know and save me having to pull one apart when time is getting hard with my move happening.

I want to carry a spare set just in case and I have a Holen set in my kit already, but thinking maybe I will just go buy a set (cheap at around $16 ATM for Trojans at Repco)

Yara has Holden bearings. Best take a spare hub with bearings in as the fit is hard to do on the road.

Thanks Ian,

Now I am wondering even more now as for 1200 I would not have expected Holden bearings, guess I will just have to do an inspection after all - Bugger.
I have considered a complete hub, so would still need to inspect and see what I have, not sure if brake disc and hub are one or separate either?

I know what's involved to change, not that I ever have had to do a trailer bearing change on road, but longtime ago I was a mechanic so no stranger to replacements and repairs. I have done early Holden rear axles though

Thanks again

OK, no need to worry anymore

I suspected this, especially if they weighing in around the 1200 and mine ATN would probably be more than that a bit, it has stuff packed into it and pushbikes in the cockpit

So what do I have, well I have early Holden PCD 4.25" (108mm) wheels
I have a 45mm square axle and Hubs are fitted with SL Ford bearings.
Lifted one axle up, and took out front bearing and that said it all without going any further and disturbing it. Looks like plenty grease and all in good nic too.
12749 written across the front = SL Ford.

Thought about a full hub, but not now as still do not really know about the discs as to if hub and disc all one or separate and no time for all that now.?

The disc and hub are one piece. The bearings are a press fit in the hub, and very hard to knock out when you are by the side of the road. The complete hubs are reasonably cheap, but you have to check that the disc is the correct diameter and thickness.
Yes Holden bearings are marginal, but then they never do anything like the design number of rotations, and are likely to fail from corrosion long before they reach their fatigue life.
